About the Kawasaki ZX550
Carburetor floats, bowl seals and airbox filters for the ZX-series GPz550.
The GPz550 name appears across more than one Kawasaki model designation. Kawasaki’s 1985 parts reference identifies the ZX550-A2, while some shared service listings also include earlier KZ550 models. For a ZX-series GPz550, the frame code and fitted carburetor bank provide the starting point for fuel-level, bowl-sealing and air-filter work.
Choose the part for the fuel-system fault
A carburetor float, bowl gasket and air filter perform different jobs. A leaking bowl joint calls for inspection of the gasket and mating surfaces; an incorrect fuel level also calls for inspection of the float and valve. The featured examples list 1984–1986, but they do not define every product on this page.

ZX550 versus KZ550 wording
Some parts are listed for both, but others are not. A shared displacement or GPz name cannot replace the exact model and year in the application.
Airbox and carburetor changes
An aftermarket intake or replacement carburetor bank can change filter and gasket requirements. Match the assembly on the motorcycle rather than assuming it is original.
